A new study by Iowa State University found that immediately performs long and moderate-intensity exercise after receiving COVID-19 or influenza vaccination, which can effectively enhance the body's immune response. studies show that performing 90 minutes of exercise can help enhance antibody response levels after 4 weeks.

Over the past few years, we have seen many related studies on "exercise can improve human health", such as inhibiting cancer cells and releasing anti-inflammatory proteins that prevent cognitive decline.
A large-scale meta-analysis of last year has revealed several interesting data. These studies, which cover more than half a million people, found that regular exercise significantly reduces a person’s risk of contracting infectious diseases.
In a new article recently published in the journal Brain, Behavior and Immunity, researchers at Iowa State University have developed a strong interest in the connection between physical activity and the immune system.
It is reported that the new research aims to pay very specific attention to "whether a single exercise will affect the effectiveness of the vaccine."
To this end, the researchers recruited some healthy subjects and gave them one of three vaccines (Influenza A/ Flu /COVID-19).
Subjects were randomly assigned to one of the groups. The experimental group required 45/90 minutes of moderate exercise within half an hour after inoculation, while the control group did not need exercise.
All participants collected blood oxygen before vaccination and then supplemented collection after 2/4 weeks to trace the effect of exercise on increased antibody levels.
results found that compared with the control group, subjects who performed exercise for 90 minutes showed significant increase in antibody levels after several weeks.
However, in the group where the 45-minute exercise was performed, the researchers did not find any difference in antibody levels between them and the control group.
In addition, an experiment conducted in mice showed that the enhancement of antibodies after vaccination showed similar differences between the 45-90-minute exercise period.
Previous studies have shown that longer exercise can produce different types of immune effects—the researchers specifically pointed out specific immune proteins called interferon alpha (IFN-α).
Early studies have found that this protein increases with the duration of exercise, and using the induced IFN-α increase hypothesis may be used to explain how physical activity becomes an immune mechanism that enhances antibody responses.
